A tuned mass damper system and vibration damper method for a hybrid electric road vehicle is disclosed. The vehicle has a powertrain with an engine, at least one electric machine and a battery. The battery mass forms a part of a vehicle vibration absorber that attenuates vibrations induced by road wheels of the vehicle.

An alternative fuel vehicle having a fuel economy control module with associated logic that allows the vehicle to operate in a fuel economy mode based on a desired fuel economy preference. The fuel economy control logic is in electrical communication with a vehicle system controller (VSC) and may be integrally formed as a sub-module within the VSC. A fuel economy control switch controlled by the fuel economy control logic toggles between an on and an off position to enable or disable a fuel economy mode. A fuel economy control selector allows a user to select a desired fuel economy mode preference once the fuel economy control switch is on. The fuel economy mode selected represents a predefined desired fuel economy preference such as a distance per amount of fuel consumed, or alternatively, a percentage of a balance between a fuel economy operation and a fuel performance operation.

An engine lubrication oil flow control system and control method for an engine in a hybrid electric vehicle powertrain is disclosed. An engine lubrication oil pump is powered by a lubrication oil pump motor. Provision is made to start the lubrication pump motor at the initiation of engine cranking upon a transition from an engine-off driving mode to an engine-on driving mode. An engine oil pressure signal is used to indicate engine filter maintenance is needed. The oil pump motor may be powered by a vehicle powertrain traction battery.

A system and method for controlling the speed of an engine includes determining a desired engine power output and engine speed, and determining whether the desired engine speed is within one of a number of predetermined engine speed ranges. It is then determined whether a noise-vibration level for the vehicle is within a target range when it is determined that the desired engine speed is within one of the predetermined engine speed ranges. The noise-vibration level is a function of at least one of a corresponding vibration level for one or more vehicle mechanical systems, and a noise level for the passenger compartment for the engine operating at the desired engine speed. The engine is then controlled at the desired engine speed when the determined noise-vibration level is within a target range, and it is determined that the desired engine speed is within one of the predetermined engine speed ranges.
